Abstract: 10 mol % Gadolinium-doped ceria (GDC10) is a highly technological relevant material with potential application in electrochemical cells, oxygen transport membranes as a catalyst and other. However, one major drawbach associated is that the processing of GDC10 requires high sintering temperatures (1300$^{\circ}$C-1600$^{\circ}$C) with dwelling time of several hours of GDC ceramics, carefully study of the sintering conditions and optimization of sintering parameters are required. The objective of this dissertation work is to understand the influence of electric field and current on the densification behaviour and microstructure evolution of GDC10. Furthermore, optimization of the sintering parameters for GDC10 powders and tailoring the microstructure by controlling the material synthesis and processing conditions were investigated. [...]
